Collaborative Learning: Think-Pair-Share

among students and shared responsibility for academic achievement” [Stein, R.

7. What is Fertilization? The students will answer the ff:
8. Where does fertilization occur?  For male (male gonad or testis,
sperm duct, and penis)
 For female (female gonad or ovary,
oviduct, and vagina)

The students will answer:

(ELICIT)  Fertilization is when a man’s sperm
combines with a woman's egg to form
a single cell. It’s one of the first steps
toward pregnancy, but there are more
hurdles to cross.

 Some people think fertilization happens

in the uterus, since that’s where the
baby develops. However, fertilization
actually occurs in the fallopian tubes.

 Each sperm has a single goal: to meet

up with the egg. To reach the target,
though, a sperm cell has to go on a
lengthy and strenuous journey.

 it must make its way from the vagina

to the cervix, and then it has to swim
through the uterus to the fallopian
tubes. Once there, if the sperm is the
lucky one, it will penetrate the egg and
fertilize it. The newly fertilized egg (now
called a zygote) will make its way from
the fallopian tubes to the uterus. There,
it will hopefully implant in the uterine
wall and grow into a baby.

development, from conception to
birth, to each group.
3. Their assignment is to create a
presentation (role play, newscast,
presentation, etc.) about the stages
of human growth that they will
present to the class.
Each team will have 3 minutes to
present their task.
4. This activity is worth 50 points.

Following the game, the teacher will

have brief discussion about the
stages of human development.
